Patent CA-2329806-C (CA)
Inventor: RICHARDS MARK R
IPC: D21F11/00
Filed: 1999-05-18
Granted: 2006-08-01
Abstract: A process for increasing bulk of a foreshortened fibrous web comprises adding moisture to at least the web's selected portions, thereby causing the crepe in the selected portions to relax and the selected portions to expand, while retaining the crepe in the rest of the web. A preferred apparatus comprises a pair of opposite surfaces, at least one of which having expansion conduits therethrough, the web being impressed between the surfaces. A temperature differential is created between the two opposite surfaces, sufficient to drive the moisture added to the selected portions therethrough, thus relaxing crepe in the selected portions which expand into the expansion conduits, while the crepe is retained in the rest of the web impressed between the two surfaces.

Title: Printed or etched, folding, directional antenna
Inventor: PALMER WILLIAM ROBERT
IPC: H01Q3/01
Filed: 2001-08-02
Granted: 2011-01-11
Abstract: An antenna array formed on a deformable dielectric material or substrate includes a center element and plurality of radial elements extending from a center hub. In the operative mode, the radial elements are folded upwardly into an approximately vertical position, with the center element at the center of the hub and the radial elements circumferentially surrounding the center element. In one embodiment the center element serves an active element of the antenna array and the radial elements are controllable in a directive or reflective state to effect a directive beam pattern from the antenna array. When not in use, the antenna elements are deformed into a plane and can therefore be integrated into a housing for compact storage. In a phased array embodiment, the center element is absent and the plurality of radial elements, are controllable to steer the antenna beam.

Abstract: This pressurized-gas storage assembly includes a pressure vessel having a ga s storage chamber and access opening, a polar boss extending through the acces s opening, a plastic liner lining the gas storage chamber, and a fitting body. The plastic liner includes a nipple portion that extends into the polar boss , terminates at an annular rim, and has a screw-threaded radially inner surfac e region. The fitting body includes a head portion, an extension longitudinall y extending from an end of the head portion and having a screw-threaded radial ly outer surface region, and an annular shoulder. The annular shoulder has an annular recess formed therein, with a compressible O-ring being accommodated within he annular recess. By inserting the extension through the access opening and positioning the screw-threaded radially outer surface region of the extension into mechanical engagement with the screw-threaded radially inner surface region of the nipple portion, the O-ring is compressed between the annular shoulder of the fitting body and the annular rim of the liner. A s a consequence, the O-ring is compressed and a hermetic seal is established between the inner liner and the fitting body, thereby preventing escape of stored compressed gas through the access opening.

Granted: 2008-06-17
Abstract: Bolt hole stress in rotor disks having bolted joints is reduced by passing relatively hot secondary flow path air (such as compressor discharge air) through each bolt hole (70) to heat the disk (40) from inside the bolt hole (70). In doing so, the temperature distribution in the area of the bolt hole (70) is made more uniform and the stress is dramatically reduced. The bolted joint (52) includes a bolt hole (70) formed in a first rotor disk (40) and a bolt (66) disposed in the bolt hole (70) such that a channel (84) is defined between the bolt (66) and the bolt hole (70). A first nut (74) or abutment is attached to a first end of the bolt (66), and a second nut (76) or abutment is attached to a second end of the bolt (66). A first passage (86) associated with the first abutment (74) provides fluid communication with the channel (84), and a second passage (88) associated with the second abutment (76) provides fluid communication with the channel (84), thereby allowing the relatively hot fluid to pass through the channel (84) during engine operation.

Abstract: L'invention concerne un interrupteur manométrique (16) à membrane comprenant un élément de base (32) possédant une surface de montage (36) constituée d'un matériau isolant ; deux électrodes (38, 40) montées sur l'élément de base (32) et possédant une surface de contact conductrice d'électricité, et une membrane souple (34) dont la périphérie est fixée, de manière étanche aux fluides, à la surface de montage, sa partie centrale conductrice étant placée sur les surfaces de contact des électrodes. La membrane (34), qui présente plusieurs ondulations (66, 68, 70), est exposée à la pression extérieure. Lorsque l'interrupteur est exposé à la pression atmosphérique, la partie centrale de la membrane ne touche pas les surfaces de contact des électrodes, tandis que lorsque l'interrupteur subit une pression supérieure à la pression atmosphérique, cette dernière force ladite partie centrale à toucher les deux surfaces de contact, établissant ainsi un contact électrique entre les deux électrodes (38, 40). L'interrupteur manométrique de l'invention convient particulièrement à une utilisation avec des hydrophones, notamment pour des câbles de flûte sismique.
